我正在使用LearnDash+WooCommerce创建LMS。到目前为止还不错。现在，我想在登录用户已经购买产品时隐藏产品，以a(防止用户购买两次，b(这样我就可以为他们显示产品网格，而不必已经购买的商品。
另一个例子：如果购买了商品a的用户去商店，商品a甚至不应该为他们显示。
非常感谢！
所以，我最终找到了一个很好的解决方法：
在产品页面上，我创建了一个自定义字段，可以在其中输入课程ID。
然后，使用PHP，我检查Product并检索COURSE ID的自定义字段。
LearnDash有一个学生的快捷代码。。。因此，在检索到课程ID后，我可以为已经注册该课程的用户显示一条消息/按钮。
这是代码：
<?php
global $product;
$postid = $product->get_id();
$courseid = get_post_meta( $product->get_id(), 'ID_del_curso', true );
$html = '"]<center><div class="alreadyPurchased"><i class="fas fa-graduation-cap paddingRightM"></i> Ya te has registrado</div></center>';
$openIT = '[student course_id="';
$closeIT = '[/student]';
echo do_shortcode( $openIT . $courseid . $html . $closeIT );
?>
希望它能有所帮助！
有一个更简单的解决方案。使用此LearnDash短代码。。。
